All right, no replies.Ordered the plan and canopy anyway.Couldn't order a photocopy of the original article - Myhobbystore doesn't have an index of when plans were published.Can anyone give me a date for the Radio Modeller which the Chipmunk appeared in please?It would have been early to mid 1980'sCheersBob

The chippie has a span of 82" - 1/5 scale and should have a bit of presence in the air.

Thanks - bought a copy of the mag from magazine exchange. Makes an interesting read.

I am chuffed to bits for you - no use keeping aircraft lying in the garage, much better to get them into the air! It looks really good in the photo.

Having looked at the size of my SC 91 FS against the plan, I had started thinking about fitting a Laser 150. After reading your reply, I think that is what I will do - there's plent of space in the cowl. The polystyrene cowl which I was supplied with will get reinforced with GF and epoxy resin, otherwise I don't think it will last very long.

I have made up a set of wing ribs and cut the slots for the main spars.

Hope you have returned fully bronzed and raring to put the Chippie through its paces.

I think a lot of the cowls are polystyrene now. This is a pity because in this size of a model polystyrene is next to useless. I am planning on epoxy glassing the fuselage and can reinforce the cowl at the same time. I quite like the surface obtainable from epoxy/glass - it is excellent for applying paint to.

The slots for the main spars did not agree with the plan for the wing and I had a fair bit of adjustment to make to the outer ribs. I then marked and cut the rear spar slots from the plan which turned out to be a good idea.

Port wing is on the building board and is being webbed slowly - one of my least preferred jobs!

No rush anyway since I won't be able to spray paint it until next spring when the weather warms up my garage to allow the paint to flow.

Did you need much of the old church roof up front? It doesn't look as though it will need as much as a Spitfire - my first Mick Reeves 74" needed 1.5 pounds with an OS 91 Supass. What a job that was to fit. The replacement needed much less with a Laser 150 up front - it's flying really well.

Used to fly in these as a cadet from RAF Lynton on Ouse. I had a polish pilot take me through the up-draught from a power station cooling tower. It nearly ripped the wings off but what a ride - like being in Willy Wonka's magic lift .

Anyway I digress. Would be very interested to know Bob how you get on with the build as I'm struggling through the build of a Yak 23 at the moment but that's from a kit not from plan and even that's giving me one or two 'challenges'.

Thanks for the kind remarks,I built this model umpteen years ago and it lay in the garage all that time never flown,biggest problem at the time was its wingspan,couldn't get it in the car,every time I needed gear for a new project it came out of the Chippy.

It took Bob to provide the inspiration to get it flying and it goes very well but I need to fit my ASP 91 fs to give it some grunt.

No building for a month or more - too many family commitments.This week has seen the webbing on the left wing completed and the trailing edge fittedThe right wing has been brought to exactly the same stage.Today I set up my dihedral board in anticipation of joining the wings in the near future.Undercarriage blocks have been cut, routed and glued into place in both wings.Feeling more positive about it now!The wing is not a straightforward build nad a dihedralled building board is a must for joining the two halves. I will use 4 servos in the wing - I gave up on bell cranks years ago. Last model I used bell cranks on was my SA Bulldog - they worked well until the covering went on and the paint was applied, centring became the problem.CheersBobPS Will probably build some more this weekend, judging by the weather forecast!

Every time something gets clamped into place there's no room to do any more!

Wings fitted on to dihedralled board and joined!

Idecided to split the dihedral brace into top and bottom halves and have fitted the top half. Much easier than trying to fit the huge things shown on the plan.

Have also revised the centre sectoion leading edge to make it more user friendly.

First wing skin fitted. Would have fitted the upper skin on the left wing but I've run out of round headed pins and can't remember where I bought the last box. They were particularly good because the heads were plastic and not glass.

Will leave the glue to set overnight and should manage the right wing tomorrow.

I really need an extra bench! Either that or I need to clear up the mess on the working bench.
